I'm having trouble with this literal equation. r^2/r^2+a^2=w/x solve for w. Thanks so much for the help

I need help with this chemistry flame test lab discussion question. "List the metals used in this lab in increasing order of the energy of the light emitted." We tested BaCl2, CaCl2, CuCl2, FE(NO3)3, KCl, LiCl, NaCl, & Sr(No3)2. I'm not completely sure ho...

sponding salt. 4. the formation of the soluble salt.

I have the same assignment,I was wondering what you had put down,I was thinking of just spliting the work between Ruth and Jack that way Ruth wont be too overwhelmed? yay or nay?

P.S I attempted it and I got r^2x/r^2+a^2=w
